A Century of Understanding and Harnessing Heterosis

open access: yesPlant Breeding, EarlyView.
ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Effects of tempol on renal medullary tissue hypoxia in an ovine model of Gram‐negative septic acute kidney injury

open access: yesExperimental Physiology, EarlyView.
Abstract Renal arterial infusion of tempol (RAT) at the onset of Gram‐negative sepsis can prevent sepsis‐induced medullary tissue hypoxia and acute kidney injury (AKI). However, it is not known whether treatment with tempol at a clinically relevant time point of sepsis is similarly effective. Thus, we examined whether tempol can reverse renal medullary

Controlled study of autoimmunization against liver in inbred rat strains [PDF]

open access: yesGut, 1971
By prolonged immunization of an inbred rat strain with isologous liver homogenate in Freund's complete adjuvant a low grade autoimmune `cholangitis' with periductular fibrosis has been demonstrated. The lesion could be transferred to isogeneic animals by serial spleen cell injections and was associated with mild but variable delayed skin sensitivity to

Mitochondrial haplotype and sex modulate responses to endurance exercise training

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Using OKC‐HETB/W rats we demonstrate that mitochondrial haplotype influences training responses of endurance exercise. Overall OKC‐HETW rats showed greater responses than OKC‐HETB in exercise tolerance, mitochondrial bioenergetics, mitochondrial DNA (mtDNA) mutation frequencies and motor co‐ordination.

Demonstration of beat‐to‐beat, on‐demand ATP synthesis in ventricular myocytes reveals sex‐specific mitochondrial and cytosolic dynamics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Beat‐locked mitochondrial ATP transients reveal modular, sex‐specific bioenergetic control during excitation–contraction coupling. A, each action potential activates L‐type CaV1.2 channels, producing a Ca2+ influx that triggers ryanodine receptors (RyR2) and elicits SR Ca2+ release.

Advancing Thermotolerance in Beans: Integrating Physiology, Genomics, and Breeding for Climate Adaptation

open access: yesLegume Science, Volume 8, Issue 3, September 2026.
ABSTRACT Rising global temperatures increasingly threaten bean production and the food security of millions of people who depend on these protein‐rich legumes. Heat stress during the reproductive stages induces pollen sterility, flower abscission, and disruptions in source–sink relationships, resulting in yield losses of 30%–40% or more when critical ...

Sleep Deprivation and Neuronal Hyperexcitation Share Transcriptomic Signatures

open access: yesNeuropsychopharmacology Reports, Volume 46, Issue 3, September 2026.
This study demonstrated that sleep deprivation induces transcriptomic changes in mice and rats similar to those observed in various models of neuronal hyperexcitation. These findings suggest a potential link between sleep deprivation and neuropsychiatric disorders.

Squash silverleaf disorder and whitefly (Bemisia tabaci MEAM1) infestation: Implications for plant disease management in a changing climate

open access: yesAnnals of Applied Biology, Volume 189, Issue 2, September 2026.
Squash Silverleaf Disorder (SLD) is growing in its economic impact due to the invasive behaviour of the silverleaf whitefly (Bemisia tabaci MEAM1). In this review we summarize what is currently known about the whitefly‐squash interaction, how both the disease and the whitefly are being affected by climate change, and discuss current and novel ...

Improvement of Mouse Spermatozoa Freezing at −80°C With Ascorbic Acid 2‐Glucoside at Thawing Phase

open access: yesAndrology, Volume 14, Issue 6, Page 1647-1655, September 2026.
ABSTRACT Background Sperm cryopreservation is the most common method to maintain a great number of mutant mouse lines. However, the use of liquid nitrogen (LN2) for freezing presents considerable problems in terms of cost, safety, and accessibility. For this reason, the storage of semen samples at ‐80° in ultra‐freezers has been increasingly used in ...

“Yet the Problem Remains”: Why Genetic Determinism Still Haunts Biomedical Research

open access: yesBioethics, Volume 40, Issue 7, Page 658-666, September 2026.
ABSTRACT After the horrors of the Holocaust and its connections to eugenics were revealed to the world, many post‐war population geneticists sought to establish rhetorical distance from the Nazi's state‐led campaigns, without abandoning their belief that actively shaping the population's genetics would produce a prosperous society.
